The facts:

The MonoWave is a project of Paul Maddox, England. He is a PPG fan, technician and musician and combined these subjects to a well done synth. He released and sold a limited run of 25 units in 2002.
The facts:

velocity may be routed to the filter cutoff and the volume by a dedicated knob for each of them

built in arpeggiator with different modes. For example a mode including a ovtaving of each note. Not after each whole sequence.
Press the notes c, e, and g:
mode B:c, e, g, c+1, e+1, g+1
mode C: c, c+1, e, e+1, g, g+1

You will always see what you will hear due to the fact it has no patch storage. But the global data (Midi channel, selected waveshapes, ARP settings and retrigger mode) will be stored.

...

A very pleasing sound. It got the special "umpf!" (hello to Ray)

because the production run is limited to 25 units only, you should test this synth now. I may demonstrate this synth (Germany only). And I don't get paid for this, I "just" love this synth.

Your browser does not support the audio element.

Only 4 (four) notes used. The first MonoWave plays a 16th note arpeggio of the notes C, G below, A flat a half step above and another C one octave below the first. The second MonoWave plays the same notes as whole notes.
Later you will hear those notes played as a Waldorf Q pad. And then the Waldorf rackAttack plays a rhythm. Everything was played live and syced to midi clock
